CARDOR SHEET PLATENl FOR TYPE-WRITING MACHINES.

SPECIFICATION forming part of Letters Patent No. 709,005, datedSeptember 16, 1902- Application tiled April 30, 1901. Serial llo.58,182. (No model.)

This invention relates to type-writing ma` chines, and has specialreference to an im"- proved card and sheet platen designed to facilitatethe handling of card and sheet work particularly.

The object of the invention in one aspect` thereof is to produce aplaten having a complete equipment of work holding and guiding means forfacilitating the guiding of different classes of work to a properprinting position upon the platen and the secure holding of the Work insuch printing position duringr the manipulation of the printingmechanism. In the concurrent application of Herman F. Eckert, Serial No.36,733, is described and claimed a platen which it is the special objectof the present invention to improve. The Eckert platen as described inthe application aforesaid is characterized by the pro vision ofwork-holding guides disposed upon the platen between the main tracks orguides for the traveling machine-frame of a book type-writingmachine,said holding-guides being designed to engage the opposite edgesof` a card or sheet and to guide the work to the proper printingposition, where it is held by the guides during the imprinting of thedesii-ed data upon the index-card Orlettersheet,

as the case may be. It is well understood in the art that index-cardsand similar Work vary in size, shape, thickness, and ruling, accordingto the purpose for which they are adapted, and the Eckert platen isespecially designed to meet these different requirements by providingmeans for insuring accuracy in printing upon the card or sheetirrespective of the size, shape, or ruling thereof. This means, as shownin the application aforesaid, embraces holding guides or guideways forthe work which are automatically adjustable or variable to accommodatedit'- index-cards of different qualities. These guides are formed bycooperating t relatively movable sections or strips between which theedge of the work is received, one ofthe strips being resilient to permitthe yielding thereof as the card is moved along the guides to itsprinting position.' The Eckert platen is highly efficient for thehandling of cards and also facilitates the positioning and retention ofletter-sheets in the proper printing position. There are some uses,however, for which the Eckert platen is not entirely available. Forinstance, if the paper is particularly thin or if a number of carboncopies are required the moviugof the Work to its proper printinglposition, with its edges engaged by the guides, is attended with more orless difficulty and cannot be done with the despatch which is highlydesirable in the practical operation of typewriting machines.

The primary object of the invention now under consideration is toimprove the Eckert platen in a manner to facilitate its use for a widerrange of work, but more particularly for the securing of a number ofcarbon. copies ofthe letter or other sheet upon which the printing isdone.

To this end the invention contemplates the provision of work-holdingmembers formed with guideways for the opposite edges of the work,substantially in accordance with the Eckert guides, and also capable ofbodily movement toward and away from the Writingsurface for the purposeof clamping the" edges of a'number of sheetsas, forinstance, an originaland several carbons,which are thereby positioned upon the platen-that isto say, the present invention contemplates workholding members which maybe utilized as clamps to engage and retain the edges of the letter-sheetimposed directly upon the platen or a plurality of work-sheets and thealternating carbon elements which are necessarily employed im making asingle original and a number of carbon copies thereof simultaneously.Subordinate to this general object is the provision of work-holdingmeans which will not only hold a number of superimposed sheets inposition upon the platen, but which will permit the edges of the severalsheets at one side of the writing-surface to be released, so that thcseveral sheets may be corrected by ICD held by the other clamp, whichlatter main-- taius the proper registering relation of the severalsheets during the making of such corrections as may be desired.

With these and other objects in view, all as will more readily appear asthe nature of the invention is better understood, the same consists inthe novel construction, combination, and arrangement of partshereinafter more fully described, illustrated in the accompanyingdrawings, and succinctly defined in the appended claims.

In carrying the invention into effect the illustrated structure isnecessarily susceptible to a wide range of modification withoutdeparting from the spiritor scope thereof; but the preferred embodimentof the present improvements is shown in the accompanying drawings, inwhich- Figure l is a perspective View of a card and sheet platen fortype-writing machines equipped in accordance with vthe presentinvention. Fig. 2 is a longitudinal section on the line 2 2 of Fig. l. YFig. 3 is a bottom plan view of the platen.. Fig. 4 is a longitudinalsection on the line 4 4 of Fig. Fig. 5 is a transverse sectional view onthe line 5 5 of Fig. 3. Fig. 6 is a similar View on the line 6 6 of Fig.3. Fig. 7 is a transverse sectional view on the line 7 7 of Fig. 3 andshowing the work guiding and clamping members swungtotheiruprightpositionsindottedlines. Fig. 8 is a perspective view ot'the adjustable work guide and clamp and ot' the mounting thereofdetached, and Fig. 9 is adetail set-tional View on the line 9 9 of Fig.3.

The work holding and guiding means constitutingthe subject-matter of thepresent application are particularly designed for use in connection withthe flat platen of a book type-writing machine and possess specialutility in connection with the type of platen illustrated in thedrawings and designated by `the numeral l. This platen is of the samegeneral character as that shown in the Eckert application and employedcommercially in connection withthe Fisher book type-writing machines, atype of which is illustrated in my Patent No. 573,868, and theinvention, while being designed primarily as an improvement of theEckert platen, is intended for the same general purpose as thatdisclosed in the pending application of H. J. Halle, Serial No. 732,921.Inasmuch as the platen per se is of a type well known in the art, adetailed description thereof is unnecessary; but, as has been premised,the presentimprovements are intended to render the platen distinctivelyeiicient for card and sheet work, and particularly for the purpose ofmulticopying. As usual, the platen 1 is provided with a plurality ofpendent rest-feet 2 at the under side thereof and with the usual trackrails or guides 3 for the reception of the printing mechanism designedto travel over the upper surface of the platen, it being immaterial sofar as the present invention is concerned whether the rails or guidesare separable from the platen or permanently attached thereto, as in thevarious kinds of plateus employed with the Fisher book type-writingmachines.

The invention comprehends the employment of work holding and guidingmembers or work guides and clamps arranged in one or more pairs inproper relation to the traveling printing mechanism and its platen andhaving guiding and holding means for the edges of the card or sheet andalso constitilting clamps for holding a number of sheets' in positionupon the platen when multicopying is desired, whereby the work may notonly be guided to and held in the proper position for being printedupon, but in the case of multicopying will also be held in a manner topermit the original and the several carbon sheets of copies to be turnedback to facilitate the making of erasures and other corrections withoutinterfering with the registering relation of the several sheets.

ln that embodiment of the invention illustrated in the accompanyingdrawings is shown a pair of work-holding members, which may betermed work guides and clamps, arranged longitudinally of the platenover the Writing-surface thereof and disposed in substantialparallelism. These combined clamps and guides4and 4tL may be variouslymounted upon the platen; but it is desirable that the mounting be suchas will permit the guides to have a wlde range of relative adjustment toaccommodate work of widely differing sizes and to permit practically theentire platen or any part thereof to be utilized as the printing area.This wide range of adjustment is preferably accomplished by tixedlypositioning one of the members or guides-as, for instance, the member4a-at a point contiguous to one edge of the platen and adjacent to oneof the machine rails or guides 3 and by mounting the other member orguide 4 in a manner to render it capable of transverse adjustmentbetween the fixed member or guide and the machine-rail 3 at the oppositeside of the platen. To permit this adjustment of the member 4, thelatter may beslidably mounted through the medium of instrumentalities ofvarious forms, one of which is illustrated in the Eckert application;but itis preferable to mount the member or combined clamp and guide 4upon a sliding carriage comprising a slide block or stem 5, disposed atone end of the platen, a slide 6, disposed at the opposite end thereof,and a flat plate or strip 7, extending longitudinally of the platenagainst the under face thereof IOC) IIO

' and secured at its opposite ends, as by screws or other suitablesecuring means 8, to the slides and 6. (See Figs. 3, 5, 8, and 9.)

.The slide block or stem 5 of the carriage is platen 1 and extendingtransversely from side to side thereof. The slide 5 projects laterallybeyond the guide 4 and is retained in its adjusted positions within theslot 9, as by a binding-screw 11, disposed below the platen and screwedinto the slide or block 5, so that when the screw is tightened againstthe under side of the platen it serves to lock and hold the slide infixed position, and thereby effects the retention of the member 4 in anyposition to which it may have been adjusted over the platen for theaccommodation of any character of work. The slide 6 of the carriageinstead of being housed within a guide-bar is .located against the rearedge of the platen defined at the front side of the usual dropopeningand is provided with a tongue 12, (see Fig. 8,) engaging a groove 13iinthe under face of the platen, so that whenthe binding-screw 11'isloosened the carriage for the Work-holding member 4 may be readilyadjusted transversely in an obvious manner.

The use of the members 4 and 4fL as workclamping means necessitates thebodily movement of said members toward and away from the platen.Obviously such movement of these `parts may be effected in many ways;`

but in the practical construction of the platen for card or sheet workthe holding members `or guides 4 and 4 are arranged over theprinting-surface and are hinged at their' outer or opposite longitudinaledges, so that they may be swung into an upstanding position over anaxis running in the direction of their length and substantially parallelwith the main tracks or guides. When these members are used for holdinga number of sheets, as inmulticopying, the clamp may be removed fromeither side edge of the sheets to permit `the latter to be folded backwhenever the operator desires to examine or individually manipulate anyone of the several sheets without disturbing its registering relationwith respect to the others.

The hinging of the holding members or guides is effected in the presentembodiment of the invention by providing said guides at` that byA meansof this mounting the work- The convenient manipulation of theworkholding members is facilitated by the `provision of thumb-plates 19and 20, carried by the forwardly-projecting ends of the trunnions 14 and15 and disposed slightly in advance of the front end of the platen, asindicated in Figs. 1, 3, and 4. These thumbplates are suitably formedfor engagement by the thumbs of the operator and are employed inswinging the members or clamps 4 and 4 upon their axes. `For some usesthe members or'clamps would alone be sufficient without the operatingmeans described; but it is preferable-to employ means for facilitatingthe manipulation of theseclamps, and it is also desirable to equip theplaten with means for eectually retaining the work-clamps in eithertheir depressed or elevated positions. Such retaining means are embodiedin the illustrated structure in the form of a pair of springs 21 and 22,secured at their lower ends to the lower ends of bracket-plates 23,depending from the slide 6 and the block 18, respectively, and locatedsubstantially in the vertical planes of the axes ofthe swinging members,so that the points of attachment of the lower ends of the springs willbe substantially in the vertical planes of the axes of movement of saidparts. (See Figs. 6 and 8.) The opposite ends of the springs 2l and 22are connected to the rear ends of the clamps at a suitable distance fromthe axes of th-e latter. (See Fig. 6.) When said members or clamps aredepressed to their holding positions, they will be yieldingl)7 retainedby the springs against upward movement. These springs are designed,however, to perform the function of retaining means for the clamps inboth the depressed and elevated positions of the latter. This result isaccomplished by theparticular arrangement specified, because while theclamps are held depressed by the springs it is evident that when theformer are swung to their upstanding positions, as shown, for instance,in dotted lines in Fig. 7, the upper end of each spring will be locatedin the vertical plane of its lowerI end. The clamp therefore will beheld in its elevated position by the spring until said clamp or memberhas been swung inward suiliciently to move the upper end of the springont of alinement withthe axis of the clamp f ings is not essential tothe present invention IIO except as noted, since in one aspect theinvention resides, broadly, in the equipment of the platen with aWork-clamp adjustable over the platen and movable toward and away fromthe Writing-surface. In another aspect of the invention, however, itembraces the idea of one or more Work-engaging members having thecharacteristics of both a workclamp and card-guide. It is thereforedesirable to equip said members with Work-guiding means designed to beemployed more particularly in connection With cardwork. In fact, Iprefer to construct these individual members substantially in the mannershown in the Eckert application aforesaid-that is to say, theWork-holding members or combined clamps and guides each consist of astraight elongated body p rovided at one edge with a guideway 24, closedat the upper and lower sides thereof to form a complete housing for theedge of the card or sheet slidably engaged therein, and said guideway ispreferably open at both ends and extends the full length oftheguide-body to permit the entrance of the individual cards or sheets atone end and their displacement or delivery from the opposite end. Tofacilitate the eutrance of the individual cards or sheets to theguideways 24, the latter preferably terminate short of the front ends ofthe holding members or guides, and beyond such point of termination thelatter are provided with elevated entrance-guides 25 of the characterillustrated in both the I-Ialle and Eckert applications heretoforeidentified.

The automatic self-adjustment of the holding-guides is effected byconstructing each of the members with a base-strip 26 and a yieldingsection or strip 27, arranged in superimposed relation to the strip 26and preferably formed of spring sheet metal having sufcient inherentresiliency to permit the retention under pressure of such cards orsheets as maybe placed in the guideways 24, the requisite delicacy ofaction of the sectional plate 27 being insured by forming the latterwith a plurality of weakening-openings 28, as shown more clearly in Fig.8. This specific construction of the work holding and guiding members 4and 4a is preferable, because by the provision of the guides for theedges of the card or sheet said members may be employed either asWork-clamps for a single sheet or for multicopying or may be utilized asholding and guiding means for cards, which latter are used extensivelyin card-indexing systems and for other commercial uses. This particularconstruction is notessential, however, except as it contributes to theembodiment of the broad idea of one or more Work-clamps independentlymovable toward and away from the platen and disposed to engage the edgesof the work at opposite sides of the printing area or to the embodimentof theinvention in that aspect wherein it contemplates the employment ofcombined clamping and guiding members capable of being manipulatedeither for the guiding and holding of cards or the like or the clampingand retention in registering relation of a number of superimposedsheets, as in multicopying.

In a still further development the invention contemplates within itspurview the additional equipment of the platen by the pro- .Visionthereon of a work alining or guiding device designed to facilitate theaccurate aliuement or positioning of the sheet or sheets and disposed incooperative relation with one of the guiding and clamping members toaline and clamp the sheet or sheets. One embodiment of such gage deviceis illustrated in Figs. l, 2, and 7 and comprises a number of upstandinggage-pins 29, arranged in longitudinal series upon the platen Within thevertical plane of the clamp and guide member 4, the base section orplate 26 of the latter being formed with openings 30 for theaccommodation of the gage-pins and arranged 0pposite the openings 28 inthe yielding upper section or plate 27 of the member. When the platen isdesigned for use in connection with card-Work, the clamp and guidemember 4 are adjusted transversely to the desired position and the cardsare fed to the printing position in a manner well understood in the art,the members 4 and 4n being held fiat upon the upper surface of theplaten by the springs 2l and 22. If now itis desired to secure a numberof carbon copies of the letter, the original and the several copysheets,together with the alternating carbon elements, are placed upon theplaten, the clamp and guide members having first been raised to theirupstanding or elevated positions, as shown in Fig. 7. The several sheetsare properly alined by abutting the edges thereof against the gage-pins29, and the clamps are turned down to the full-line position of Fig. 7to engage the opposite side edges of the sheets. After the printing hasbeen completed the sheets may be readily released by again throwing backthe clamps, or if during the printing operation an error is made theclamp and guide member 4 may be elevated and the sheets turned backsuccessively to facilitate their inspection and correction withoutdisturbing the member4, which during this manipulation of the sheetsretains the latter at one edge, and thereby prevents their beingaccidentally moved out of registering relation. After the necessarycorrections have been made thesheets are again turned down to theiroriginal positions, and the clamp member 4 is returned to its holding orengaging position to permit a continuance of the printing operation.

Of course the reversing of the cards where the platen is used forcard-indexing will be eifected, as usual, by the trip-ledge 31, Withwhich the platen is equipped, and the positioning of the cards andperhaps of the sheets will be facilitated by the disappearing stops 32,located at the rear end of the writing-surface of the platen, or by asuitable alining-guide Vlocated at the front edge of the platen; but asthe trip-ledge and disappearing stops constitute no part of my presentinvention and are fully described and claimed in the applica-` tion ofEckert aforesaid I do not consider it `necessary to enter into a detaildescription `trated structure as may be embraced within the scope of theprotection prayed.
